 A common question is which Diffie Hellman (DH) Parameters  should be used for Diffie Hellman key exchanges\footnote{\url{http://crypto.stackexchange.com/questions/1963/how-large-should-a-diffie-hellman-p-be}}. We follow the recommendations in ECRYPT II, chapter 16.\cite{ii2011ecrypt}
 
 Where configurable, we recommend using the Diffie Hellman groups
-defined for IKE, specifically groups 14-18 (2048--8192 bit MODP, \cite{rfc3526})
-and 19-21 (256--521 bit elliptic curve DH, \cite{rfc5903}). These groups have
-been checked by many eyes and can be assumed to be secure.
